Chile and the U.S. are signing a nuclear energy accord, despite fears of radiation spreading in Japan after a devastating earthquake and tsunami severely damaged nuclear reactors.
The accord will be signed Friday morning by U.S. Ambassador Alejandro Wolff and Chilean Foreign Minister Alfredo Moreno.
A day earlier, White House officials wouldn't even confirm the long-awaited signing, which was supposed to be a high-profile moment in President Barack Obama's visit to Chile on Monday.
With Japan's disaster unfolding, officials have stressed that the accord focuses on training nuclear engineers, not building reactors.
